CGG1-M 2022 shows 0,0°C temperature and 0% humidity

[TheZoker]

Hi there,

I have a CGG1-M 2022 with version 4.6 flashed.
It worked normal for the last couple of weeks, but starting some days ago, it showed and send the same temperature over and over again. I then removed the battery and but a new one in and since then it only shows 0,0°C for the temperature and 0% for the humidity.

Is there anything I can do to fix this?
